To simplify metadata tracking for delalloc writes, ext4 will simply claim metadata blocks at allocation time, without first speculatively reserving the worst case and then freeing what was not used. To do this, we need a mechanism to track allocations in the quota subsystem, but potentially allow that allocation to actually go over quota. This patch adds a DQUOT_SPACE_NOFAIL flag and function variants for this purpose. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> |
